I don't know anything about the card in general, but there are a few
things that might be able to help - what makes the screen look bad (more
than likely) is incorrect video timings - there's an application called
xvidtune (which can do damage when you're no careful - most of the time
it's not a problem) which adjusts your timings to make the best use of
teh screen. Also it might be worth having a read of the video timings
HOWTO - basically, the video timings tell how long to sleep before
re-displaying after passing off teh righthand side before reappearing on
the lefthand side, and similarily for top to bottom. Fixing those to
smaller sleep values widens the image.

Hope that's of some help, 
Dave.
